Recently numerical simulation of structural responses to earthquakes has been made possible and widely used for design purposes. The validity of such simulation depends, however, on how appropriate the mathematical models adopted are about structural behaviors. Thus, it is important to perform experiment-based simulation as well as seismic monitoring of actual inelastic responses. A three-story steel model structure with intentionally reduced seismic strength was successfully monitored about its inelastic responses to moderate ground motions at rhree events. These responses are compared with the results of sub-structuring pseudo-dynamic tests, in which the brace members at the first story are taken as a sub-structure and loaded by actuator. Additionally, numerical simulation based on hysteresis rule proposed for braces is also performed. Eventhough the loading in the pseudo-dynamic tests is performed quasi-statically, the simulated responses agree fairly well with the actual responses monitored.

近年来，结构地震反应的数值模拟已成为可能，并广泛用于设计目的。然而，这种模拟的有效性取决于所采用的数学模型对结构行为的适当程度。因此，重要的是进行基于实验的模拟以及实际非弹性响应的地震监测。本文对一个三层钢结构模型进行了三次非弹性地震反应监测。将这些响应与子结构拟动力试验的结果进行了比较，在子结构拟动力试验中，第一层的支撑构件被视为子结构，并由致动器加载。此外，本文还对提出的支撑滞回规律进行了数值模拟。虽然拟动力试验中的加载是准静态进行的，但模拟的响应与监测的实际响应相当吻合。
